9. Attention! Please observe the following when working inside and outside: No Solvent Gasses Should be carried to the unit. No solvent gasses should from near the unit. Set up the unit on the opposite side to the object being Sprayed. When spraying out doors, take the wind direction in to account. When working in doors there must be sufficient ventilation to ensure that the solvent gasses are carried away. A minimum distance of 6.1m(20') must be observed between the unit and object being sprayed. 10. Extraction equipment Should be installed by the user in accordance with the local regulations. 11. The objects being sprayed must be earthed. 12. When cleaning the unit, solvent should never be sprayed into a container with only a small opening(bunghole). An explosive gas/air mixture is likely to form. The container must be earthed. 13. Cleaning the unit. A harsh jet should never be used to spray the unit. In particular a high-pressure cleaner or high-pressure steam cleaner should never be used. There is a danger that water will penetrate into the unit and cause a short-circuit. 14. Pulling the trigger causes a recoil force to the hand that is holding the spray gun. The recoil force of the spray gun is particularly powerful when the tip has been removed and a high pressure has been set on the airless high-pressure pump. Therefore, when cleaning without tip set the pressure control valve to the lowest pressure. 15. The mains plug should only be disconnected from the socket when work is being carried out on the electrical components. 14. Work or repairs should only be carried out on electrical equipment by a trained electrician, even if the work is described in the operating instructions. No liability will be accepted for incorrectly installed electrics. 15. Positioning when the ground is uneven. The front of the unit must point downward so that the machine does not slip away. HAZARD: INJECTION INJURY- A high pressure stream of paint produced by this equipment can pierce the skin and underlying tissues, leading to serious injury and possible amputation. DO NOT TREAT AN INJECTION INJURY AS A SIMPLE CUT! Injection can lead to amputation. See an physician immediately. PREVENTION: · The maximum operating range of the unit is 221 BAR (3200 PSI) fluid pressure. · Never aim the gun at any part of the body. · Never allow any part of the body to come in contact with stream created by a leak in the fluid hose. · Never Put your hand in front of the gun. Gloves will not provide protection against and injection injury. · ALWAYS lock the gun trigger, shut the fluid pump off and release all pressure before servicing, cleaning the tip guard, changing tips, or leaving unattended. Pressure will not be released by turning off the engine. The PRIME/SPRAY knob must be turned to PRIME to relieve the pressure. Refer to the PRESSURE RELIEF PROCEDURE described in this manual. · The tip guard must always be in place while spraying. The tip guard provides some protection against injection injuries but is mainly a warning device. · ALWAYS remove the spray tip before flushing or cleaning the system. · The paint hose can develop leak from wear, kinking and abuse. A leak is capable of injecting material into the skin. Inspect the paint hose before each use.
NOT E TO PHYS ICIAN: Injection into the skin is a traumatic injury. It is important to theat the injury surgically as soon as possible. DO NOT delay treatment to research toxicity. Toxicity is a concern with some coatings injected directly into the blood stream. Consultation with a plastic surgeon or reconstructive hand surgeon may be advisable. HAZARD: EXPLOSION OR FIRE-Solvent and paint fumes can explode or ignite, causing property damage and/or severe injury. PREVENTION: · Fire extinguishing equipment must be present and in go od working order. · Use only conductive or earthed high pre ssure fluid hoses for airless applications, b e sure that the gun is earthed properly through hose connectio ns. · The pump mu st be connected to an e arthed object. U se the green earthing wire to connect the p ump to a water pipe, steel beam, or other electrically earthed surface. · When flushing equipment use the lowest possible pressure. HAZARD: EXPLOSION HAZARD DUE TO INCOMPATIBLE MATERIALS- May cause property damage or severe injury. PREVENTION: · Do not use bleach. · Do not use halogenated hydrocarbon solvents such as methylene chloride and 1,1,1-trichloroethane. They are not compatible with aluminum and may cause an explosion. If you are unsure of a material's compatibility with aluminum, contact your coating's supplier. HAZARD: GENERAL-May cause property damage or severe injury. PREVENTION: · This high pressure airless pump is designed to be used with manufacturer authorized parts only. When using this pump with parts that do not comply with the minimum specifications and safety devices of the pump manufacturer, the user assumes all risks and liabilities. · Before each use, check all hoses for cuts, leaks, abrasion or bulging of cover, as well as damage or movement of couplings. If you any of these condition exist, replace the hose immediately. Never repair a paint hose. Replace it with another earthed hose. · Wear protective eyewear. · Do not spray on windy days.
Earthing Instructions This product must be earthed. In the event of an electrical short circuit, earthing reduces the risk of electric shock by providing an escape wire for the electric current.

Avoid arcing or holding the gun at an angle ,This will result in an uneven finish.
Off spray
Too thick
Arcing
Gun at angle
Proper lapping(overlap of spray pattern) is essential to an even finish. Lap each stroke .If you are spraying horizontally, aim at the bottom edge of the preceding stroke, so as to lap the previous pattern by 50%.
Overlap edges
Spraying WARNING POSSIBLE INJECTION HAZARD. Do not spray without the tip guard in place .Never trigger the gun unless the tip is in either the spray or the unclog postion ,Always engage the gun trigger lock before removing ,replacing ,or cleaning tip.
Spraying Technique The following techniques ,if followed,will assure professional painting results. Hold the gun perpendicular to the surface and always at equal distance from the surface. Depending on the type of material, surface ,or desired spray pattern, t he gun should be held at a distance of 30 to 50 cm (12 to 14 inches) Move the gun either across or up and down the surface at a steady rate. Moving the gun at a consistant speed conserves material and provides even coverage .The correct spraying speed allows a full ,wet coat of paint to be applied without runs or sags. Holding the gun closer to the surface deposits more paint on the surface and produces a narrow spray patern.. Holding the gun farther from the surface produces a thinner coat and wide spray pattern .If runs ,sags ,or excessive paint occur, change to a spray tip with a smaller orifice . If there is an insufficient amount of paint on the surface or you desire to spray faster ,a larger orifice tip should be selected. Maintain uniform spray stroke action ,Spray alternately from left to right and right to left. Begin movement of the gun before the trigger is pulled. Start stroke
Pull trigger
5st 2st 3st 4st 1st pass pass pass pass pass For corners and edges ,split the center of the spray pattern on the corner or edge and spray vertically so that both adjoing sections receive approximately even amounts of paint. When spraying with a shield ,hold it firmly against the surface. Angle the spray gun slightly away from the shield and toward the surface This will prevent paint from being forced underneath. Shrubs next to housed should be tied back and covered with a canvas cloth .The cloth should be removed as soon as possible . our gun extensions are extremely helpful in these situations. Nearby objects such as automobiles ,outdoor furniture,etc. should be moved or covered whenever in the vicinity of a spray job.Be careful of any other surrounding objects that could be damaged by overspray .
Release End trigger stroke

PRACTICE 1.Be sure that the paint hose is free of kinds and clear of objects with sharp cutting edges. 2.Turn the pressure control knob counterclockwise to its to its lowest setting. 3.Turn the PRIME/SPRAY valve up to its SPRAY position. 4.Turn the pressure control knob clockwise to its highest setting. The paint hose should stiffen as paint begins to flow through it. 5.Unlock the gun trigger lock. 6.Trigger the spray gun to bleed air out of the hose. 7.When paint reaches the spray tip,spray a test area to check the spray pattern. Use the lowest pressure setting necessary to get a good spray pattern, If the pressure is set too high,the spray pattern will be too light. If the pressure is set too low, tailing will appear or the paint will spatter out in gobs rather than in a fine spray .
7.Submerge suction tube in water or flushing solvent.
8.Turn pressure control knob to the PRIME/CLEAN setting.
9.Turn the power switch ON.
Shutdown and Cleaning 1.Pressure Control Knobs Settings 2.Remove tip and guard assembly from gun and place in flushing fluid. 3.Lift suction tube and prime tube from paint pail Let them drain into paint pail for a while.
4.Separate prime tube (smaller) from suction tube(larger)
5.Place empty waste and water or solvent pails side by side.
10.Flush until approximately 1/3 of the flushing fluid is emptied from the pail.
11.Turn power switch OFF.
When storing the paint station for 16 hours or more, a thorough cleaning is recommended: 1.shutdown paint sprayer 2.thoroughly clean paint sprayer and station according instruction; 3.be sure that machine and tubes are clear any w ater or fluid as these may freeze; 4.Coil high pressure hose and store on back of tool with hook and loop straps; 5.Store filter spraying gun, and sprayer in plastic bag and seal;

Tip Selection Selecting Tip Hole Size Tips come in a variety of hole sizes for spraying a range of fluids. Your sprayer includes an 0.015 in (0.38mm) tip for use in most spraying applications. Use the following table to determine the range of recommended tip hole sizes for each fluid type. If you need a tip other than the one supplied, see the Reversible tip Selection Chart on page 15. HIN TS: · As you spray, the tip w ears and enla rges, Starting w ith a tip hole size sma ller than the maximum w ill allow you to spray w ithin the rated flow c apacity of the s prayer. · M aximum tip hole sizes suppor ted by t he sprayer. 0 .015om (0.38m m)
Choosing The Correct Tip Consider Coating and Surface to be Sprayed. Make sure you use best tip hole size for that coating and best fan width for that surface. Tip Hole Size Tip hole size controls flow rate the amount of paint that comes out of the gun. HINTS: · Use large tip hole size with thicker coatings and smaller tip hole sizes with thinner coatings. · Maximum tip hole sizes supported by sprayer: 0.015 in. (0.38mm) · Tip wear with use and need periodic replace-ment. Fan Width: Fan width is the size of the spray pattern, which determines the area covered with each stroke. Narrower fans deliver a thicker coat, and wider fans deliver a thinner coat. HINTS: · Select a fan width best suited to the surface being sprayed. · Wider fans allow provide better coverage on broad, open surfaces. · Narrower fans provide better control on small, confined surfaces. Understanding Tip Number The Last Three digits of tip number (i.e.:221413) Contain information about hole size and fan width on surface when gun is held 12 in. (30.5cm) from surface being sprayed. First digit when doubled = approximate fan width
